Many people are reporting this problem to me lately: when using IEs4Linux with recent wine versions (>=0.9.52), the ie toolbar disappear and others display bugs happen. Here is IEs4Linux 126.96.36.199 that fixes only this bug. It’s an emergency release since 2.99.1 is not ready yet (as you know I’m late with this due to recent personal problems). I’m now finishing 2.99.1 that will have a lot of improvements and much better Mac compatibility.
